Kids of any age love to read fairy tales because the storyline never limits the possibility that anything could happen. But are the most magical moments from some of our favorite stories actually possible? Basic physical principles and recent scientific research suggest that what readers might mistake for fantasies and exaggeration could be rooted in reality.So suspend your imagination for a moment, and look, as a hard-core scientist might, at the following fairy tale—The Arabian Nights. One of the most exciting objects found in fairy tales is the flying carpet. In tales from a wide variety of cultures, including The Arabian Nights, these tapestries (挂毯) take flight to carry people vast distances. Flying carpets are clearly impossible, right?Three scientists recently published a paper in the journal Physical Review Letters showing that there are conditions under which a carpet could fly. They used the basic laws of physics to show that a small, thin carpet could fly if the air were vibrating at the right frequency, much like how a piece of tissue paper floats softly to the ground when it is dropped. Their calculations showed that small waves of air in repeated fast pulses could steer a carpet at a speed of around one foot per second.Don't expect to see Aladdin flying by anytime soon, but the scientists write that all of their conditions are within the realm of possibilities in nature and in technology. Making a heavy carpet fly would, of course, require a much more powerful engine, and our calculations suggest it will remain in the magical, mystical, and virtual realm as it has existed for millennia (千年).68. What does the example of flying carpets show?A) Many magical moments could be realized in realityB) A small, thin carpet could fly like a piece of paper.C) There are possibilities that a carpet can fly in reality.D) Some magical things still remain mystical and unreal as before.

In a country that defines itself by ideals， not by shared blood， who should be allowed to come work and live here？ In the wake of the Sept． 11 attacks these questions have never seemed more pressing．On Dec.11， 2001， as part to effort to increase homeland security， federal and local authorities in 14 states staged "Operation Safe Travel"-raids on airports to arrest employees with false identification In Salt Lake City there were 69 arrests．But those captured were anything but terrorists， most of them illegal immigrants from Central or South America Authorities said the undocumented workers' illegal status made them open to blackmail by terrorists．Many immigrants in Salt Lake City were angered by the arrests and said they were being treated like disposable goods．Mayor Anderson said those feelings were justified to a certain extent． "We're saying we want you to work in these places， we're going to look the other way in terms of what our laws are， and then when it's convenient for us， or when we can try to make a point in terms of national security， especially after Sept． 11， then you're disposable． There are whole families being uprooted for all of the wrong reasons，" Anderson said．If Sept． 11 had never happened， the airport workers would not have been arrested and could have gone on quietly living in America， probably indefinitely． Ana Castro， a manager at a Ben & Jerry's ice cream shop at the airport had been working 10 years with the same false Social Security card when she was arrested in the December airport raid． Now she and her family are living under the threat of deportation (驱逐出境)． Castro's case is currently waiting to be settled． While she awaits the outcome， the government has granted her permission to work here and she has returned to her job at Ben & Jerry's．1． According to the author， the United States claims to be a nation___．A． composed of people having different valuesB． encouraging individual pursuitsC． sharing common interestsD． founded on shared ideals2．Undocumented workers became the target of "Operation Safe Travel" because___．A． evidence was found that they were potential terroristsB． most of them worked at airports under threat of terroristsC． terrorists might take advantage of their illegal statusD． they were reportedly helping hide terrorists around the airport3． By saying "…we're going to look the other way in terms of what our laws are" (Line 2， Para． 4)， Mayor Anderson means "___"．A． we will turn a blind eye to your illegal statusB． we will examine the laws in a different wayC． there are other ways of enforcing the lawD． the existing laws must not be ignored4．What do we learn about Ana Castro from the last paragraph？___A． She will be deported sooner or later．B． She is allowed to stay permanently．C． Her case has been dropped．D． Her fate remains uncertain．

Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
